Having trouble throwing with power. I,m throwing more outward than downward if that makes any sense any thoughts.thanks

Dear Tim,
Let me ask you a question-does your Uke hit the ground each time you do shiho nage?If the answer is yes, why do you need to have to throw with power?Is it not enough to simply make sure uke hits the deck? When I trained with Sekiya Sensei[ Chiba Sensei' father in law] he never at any time used powerful waza.At the same time he always pinned or threw you with ease-totally painless and safe.
Shiho nage done incorrectly with power can dislocate the collar bone and also plays havoc with the elbow joints.
Rather than try to be Rambo or King Kong,why not forsake power and acquire skills?If you receive /use power its unlikely your or your ukes body will be fit after 30 /40 years training.
your throwing direction imo is not qite right.Ask yourself the question , do you want to send uke to the floor or throw uke up in the air and thiry feet away [for example]??I would suggest you should send uke to the floor in the shortest route possible ie to the ground [downward to the mat ].
Have a nice day , Joe.
